01Feasibility & format selection
Review the target, sample matrix and intended detection range. Evaluate whether a sandwich or competitive format fits the available reagents.
Radetec / Contract R&D / Melbourne
Custom Lateral Flow Assay Development Australia
Turn a biomarker or detection concept into a practical rapid-test prototype, with assay chemistry matched to your target, sample and readout.
Development scope
From the first question
to the next milestone.
02Reagents & conjugation
Evaluate antibody pairs or other recognition reagents, prepare nanoparticle conjugates and assess binding and background.
03Strip & workflow optimisation
Optimise membranes, pads, buffers, reagent loading and sample preparation as an integrated assay.
04Prototype & analytical evaluation
Assess detection range, selectivity and repeatability against agreed criteria. Explore reader-based quantitation where suitable.
Technical perspective
What matters in development
A lateral flow assay succeeds when the target, recognition reagents, label, sample matrix and strip materials work together. We can evaluate sandwich or competitive formats, then test the most important technical risks before investing in a full development programme. For reader-assisted assays, we can investigate fluorescent quantum dots alongside gold nanoparticle labels.
Common project questions
Can you start with a biomarker but no antibodies?
Yes. The first stage can review the target, sample type and required detection range, then identify the recognition reagents and assay format that need evaluation. Feasibility depends on reagent availability and target biology.
Do you develop competitive lateral flow assays?
We can evaluate competitive formats for targets such as small molecules when a conventional sandwich assay is unsuitable. The format and reagents are assessed during feasibility.
Can you help improve an existing strip?
Yes. We can investigate background, weak signal, matrix effects, conjugation, membrane choice and reader performance against your current baseline.
For fluorescence-based assays, see our dedicated quantum dot lateral flow development service.
